There is no better way to describe Edward Kennedy Ellington and his impact on the world of music than to cite this splendid article by Leonard Feather, in 1950:
DUKE ELLINGTON: JAZZ PIONEER FOR 25 YEARS
It was Duke Ellington himself who gave me the idea for this article.
When a man has been as well established in the musical scene as the Duke has this past quarter century, and when so many words of praise have been written about him that every permutation of superlatives seems to have been exhausted, a problem arises.
You know that Duke is still a vitally important figure, yet you find that there is less being written and said about him than about many younger and perhaps less newsworthy entrants into the field.
It was while we were reflecting along these lines that Duke started to muse about some of the advances that have been made in jazz through the years-advances by artists in instrumental and orchestral innovations, as well as by whole bands building new ideas from the production and promotion standpoint.
